If you're a regular lister on eBay, you know how much your items are selling for, but maybe not the hard margins on your best stuff. Free (in beta) web tracker ProfBay aims to help.

ProfBay can't read tea leaves to know how much it cost you to acquire or prep an item for sale, but it does do the hard math on your shipping, eBay's insertion and listing fees, and PayPal take-outs to determine how much you're in the black after sending your item out.

The Redferret Journal said:

ProfBay is a new online application that monitors your eBay account to help you track profitability from your sales. It’s in beta at the moment, and free, but the developers plan to charge a ‘small subscription fee’ sometime in the future. Could be useful for all you budding auction entrepreneurs.

ProfBay.com is all those things, and more. So many eBay sellers sell mostly on the blind, or using clumsy, time-consuming spreadsheets. ProfBay automates this process by importing your completed listings, and giving eBay sellers an overview of how their eBay businesses are doing.

Main features:

Automatic importing of eBay listings

Automatically tracks all expenses, fees, and income

Other income and expenses (including acquisition costs) can be added by the user
